Offered by: Family Naturopathic Clinic
A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs).
Classifications
There are eight blood groups and they are classified using two systems.
• ABO System
• Rhesus system
ABO System – is the most important blood-group system in human-blood transfusion
It has four main groups:
• O Group
• A Group
• B Group
• AB Group
Rhesus System (RhD) – is the second most significant blood-group system in human-blood transfusion with currently 50 antigens; the most significant Rh antigen is the D antigen, because it is the most likely to provoke an immune system response of the five main Rh antigens
It is classified as Rhesus Positive (+) and Rhesus Negative (-). The two systems combine to define the following of eight different blood groups of O-, O+, A-, A+, B-, B+, AB- and AB+.
Blood Group Compatibility
The table below demonstrates blood type compatibility. A person with AB+ blood type can receive blood from all of the major blood type groups. At the other extreme people with O- blood type can only receive blood from donors with the same blood type.
